Question

Mary is making a pinata that has a ball-like shape. The pinata has a surface area of

60 square feet. Use the formula for the surface area of a sphere:
S=471?
to find the radius of the pinata in feet.

Answer 1

2.19 ft

Explanation:

The formula for the surface area of a sphere = 4πr²

Surface area of the sphere = 60 ft²

The formula to find the radius of a sphere

= √A/4π

= √60/4 × π

= 2.19 ft

Therefore, the radius of the pinata = 2.19 ft
